TELEVISION CAMERA TUBE

摘要

A television camera tube is provided with a discrete structure of photosensitive elements provided on an electrically conductive carrier. By applying to the conductive carrier a potential which is suitable for that purpose, which carrier is covered entirely with photoconductive material or another resistance material, a potential distribution occurs having successive saddle points for the scanning beam. Variation and exposure of the discrete photoconductive elements then results in a variation in beam splitting in the saddle points. As a result of this a greater or smaller extent of natural amplification can be given to the tube.
